SPECT-CT

April 2, 2018 – The Canadian Nuclear Safety Commission (CNSC) announced March 29 that it renewed Canadian Nuclear Laboratories’ (CNL) Nuclear Research and Test Establishment Operating License for the Chalk River Laboratories (CRL) site.

February 8, 2018 — The U.S. Food and Drug Administration (FDA) and the Nuclear Regulatory Commission (NRC) recently took steps to ensure a stable and secure supply of a critical radioactive imaging tracer used to detect potentially life-threatening diseases.

Prem Soman, M.D., director of nuclear cardiology at the Heart and Vascular Institute, University of Pittsburgh, and president-elect of the American Society of Nuclear Cardiology (ASNC), explained advances in PET and SPECT imaging and the learning curve involved in reading scans from the new CZT...

David Wolinsky, M.D., director of nuclear cardiology at Cleveland Clinic Florida and past-president of the American Society of Nuclear Cardiology (ASNC), discusses advancements in nuclear imaging and some of the issues facing the subspecialty.

A suspected pulmonary embolism on a conventional CT image (left (or top), red arrow) is confirmed on a spectral CT by the presence of a corresponding wedge-shaped perfusion defect (right (or bottom), red outline). The spectral image was reconstructed when conventional CT images were not enough to form a definitive diagnosis. All data was acquired simultaneously using a Philips IQon Spectral CT scanner.

Dual-energy scanning, achieved on Siemens’ Definition Edge, reduces severe artifacts caused by an implanted pump (left), clearly visualizing surrounding anatomical structures (right). The twin-beam, single-source Edge is one of several platforms that can characterize tissues and structures according to the atomic numbers of their elements. (Image courtesy of Siemens Healthcare)
